Novel technique to enhance flow of medication during cervical interlaminar epidural steroid injections

Epidural steroid injections (ESI) are widely used interventional pain procedures to treat conditions like radiculopathy and spinal stenosis. Cervical ESIs were previously performed via transforaminal or interlaminar approaches; however, transforaminal cervical epidural injections have declined due to risk of brain and spinal cord infarction from intravascular uptake of particulate steroids[1], leading to the interlaminar approach as the standard. This study proposes an alternate technique to enhance the efficacy of interlaminar cervical epidural injections.
